C# 如果项目不在数组中

Question

我有一个包含这 3 个项目的数组:

string[] departmentArray = {
    "Warranty Service Representative",
    "Warranty Service Administrative Manager",
    "Warranty and Site Administrator"
};

我有这个字符串

var department = "Warranty Service Representative"

我有这个条件，假设要测试字符串 department 是否不在 departmentArray

中

if (Array.Exists(departmentArray, element => element != department)){
}

很明显字符串在数组中，所以它应该返回 false，但这对我的字符串返回 true。我做错了什么？

Answer 1

这不是更简单吗？

string[] departmentArray = { 
    "Warranty Service Representative", 
    "Warranty Service Administrative Manager", 
    "Warranty and Site Administrator" };

String department = "Warranty Service Representative";

if (departmentArray.Contains(department) == false)
{
}
